Chromium processing Britannica. Pure chromium is produced either by the thermal reduction of Cr 2 O 3 with aluminum or by the electrolysis of trivalent chromium solutions. The aluminothermic process begins with the roasting of fine ore, soda, and lime in air at 1,100 °C (2,000 °F).
aluminothermic reduction reaction is spontaneous and the entire reaction gets com-pleted within a few ntiniutes. It is estimated that for the process to be self sufficient in its heat requirements and good separation of metal and slag, the specific heat effect of the process should be 650-750 K calories per Kgm of reacting substances. Experimental
Calcium metal was successfully produced from Egyptian limestone ore under vacuum using aluminium as a reducing agent. The aluminothermic reduction process of CaO by aluminium metal was followed up by collected amounts of produced calcium metal.
Chromium is an extremely versatile element and finds a wide variety of uses in applications in the steel and alloys, chemical and refractory industries. There are two ways of producing chromium metal, by aluminothermic process from chrome oxide and by electrolytic process using ferrochromium or …

A method of conducting an aluminothermic reduction of an oxide of a reactive metal comprising melting in a vessel in an induction furnace a conductive susceptor metal and thereafter adding the required intimately mixed reactants to the molten mass in the container wherein the rate of addition of the reactants and the power input to the induction furnace are controlled to maintain the ...
The chromium-rich residue of such a direct leach process would be treated to produce chromium metal using fluidized-bed roasting and aluminothermic reduction. The major advantage would be elimination of the magnetic separation and froth flotation operations, which were found to be rather inefficient.
c) This purified chromic oxide is well suited to reduction by the aluminothermic process to produce pure chromium metal that meets ASTM Specification A 481-97. d) The goal of producing aluminothermic chromium metal that meets the ASTM specification for Grade A metal was essentially achieved in this feasibility study.

The geologic sources of chromium are essentially mixtures of spinels of the ideal form RO·R 2 O 3 (e.g., chromite is FeO·Cr 2 O 3), although a more accurate representation of an ore source would be (Mg,Fe)Cr 2 O 4 with silica and alumina gangue materials. The refining processes for chromium metal have been thermodynamically defined by their spinel origins.
